FILING MACHINE.

Original application filed January 12, 1923, Serial No. 612,176. Divided and this applieation filed October 29, 1925.

My invention relates to machines for throwing and'piling fabrics such as for instance lace curtains, and has for its object to provide a novel and simple machine for automatically piling fabrics in predetermined lots and more particularly for piling lace curtains in kier lots for transference to the lrier in the process of producing lace curtains. Other objects of the invention will appear from the description hereinafter, and the features of novelty will be pointed out in the claims. The present application is a division of another application filed by me in the United States Patent Office on January 12, 1923, Serial No. 612,176.

Reference is to, be had to the accompanying drawings, which illustrate an example of the invention without defining, its limits, and in which Figure 1 is a diagrammatic view illustrating the novel machine'in use for piling curtainspFigure 2 is a front view partly in; section of the machine, and Figure 3 is a side View thereof partly in section.

.As shown in the drawings, the machine, which may be termed a rapid piler, comprises a frame 10 preferably suspended by means of rollers 11 from a track 12 and provided at. its lower portion with a guide roller 13 arranged to engage and travel along a rail 14 to maintain the frame 10 againstvibration and in its intended path. A drum 15 is carried by a-shaft 16 jourmilled in suitable bearings 17 secured at the proper places upon the frame 10; the shaft 16 carries also pulley 18 which is connected by means of a belt 19 with a pulley 20 secured uponthe shaft of an electric motor 21 mounted upon the frame 10, as shown in Figure 2. A pressure roll 22 is located in surface engagement with the drum 16 and is carried by a shaft 23 journalled in bearing blocks 24 slidably mounted in guides 25 forming part of or secured to the frame 10 for the purpose of maintaining the pressure roll 22 under pressure towards the drum 15, springs 26 are provided which preferably surround stems 27 connected with the bearing blocks 24 and slidable in guides 28, 'as shown in Figure 3. In the preferred construction the surfaces of the drum 15' and pressure roll 22 are covered with a hard wool felt of suitable thickness or are otherwise treated to cause the drum Serial No. 65,540;

may be provided for pivotally reciprocating said deflector in a gradual and continuous manner; for instance, the mechanism illustrated in Figure 3 may be utilized for this purpose. This mechanism comprises a suitable cam 33 mounted upon a shaft 34 journalled in bearings 35 located upon the frame 10, said shaft 34 further carrying a worm gear 36 which meshes with a worm pinion 37 fixed upon a countershaft 38; the latter is rotatably mounted by means of bearings 39 upon the frame 10 and is provided with a bevel gear 40 meshing with a bevel gear 41 located upon the drum shaft 16 whereby said worm gearing and cam are operated. A roller 42 arranged to engage the cam 33 is mounted upon a camfollower arm43 depending from a shaft 44 journall'ed in bearings 45 upon the frame 10- and having its free end connected by means of a strap 46 with one of the arms 30, as shown in Figure 3. The roller 42 is maintained in operative engagement with said cam 33 by means of a spring 47 which has its one end attached to a convenient portion of the frame 10 and its other end connected by means of a strap 48 with the other arm 30. An operating lever 49 is fixed upon the shaft 44 and is provided at its free end with a. cord 50 which depends therefrom within easy reach of the attendant. At a point'in registry with the drum 16 and roll 22, the machine is provided with a pot-eye 51 which is supported upon the frame 10 by a bracket 52 for guiding the lace to said drum, as will appear more fully hereinafter.

In practice, this machine is operated by the motor 21, which transmits motion through the medium of the pulleys 20 and 18 and belt 19 to the drum 15, which, in turn, because of its surface engagement therewith, imparts motion to the pressure roll 22. At the same time, as the drum shaft 16 is actuated by the motor 21 it will, through the medium of the bevel gears l0 and 1-1, operate the countershaft 38 and worm gearing 37, 36 which, in turn, brings about a rotation of the cam 33. This causes the follower arm 43 to be pivotally swung, for instance, from the position shown in Figure 3 whereby a pull is exerted upon the strap 16; this results in rocking the deflector shaft 31 and moves the deflector 29 in a circular path toward the drum 15, the spring at? being, by this operation, stretched under tension. As the cam 33 continues to operate, the follower arm 43 will finally describe a swinging movement in the reverse direction, because of the shape of said cam 33, whereby the deflector 29, by the action of the spring t? upon the strap 48 and arm 30, will be caused to move in a circular path away from the drum 15. The gradual pivotal reciprocation of the deflector 29 toward and away from the drum 15 in the manner described, is repeated throughout a given period of operation; if, at any time, a more rapid operation of the deflector 29 in a direction away from the drum 15 is temporarily desired, this may be accomplished by exerting a downward pull upon the cord 50 to pivotally actuate the lever 19 and thereby swing the follower arm 4-3 independently of the cam 33. In utilizing this machine, for instance, in piling lticr lots in the manufacture of lace curtains, a roll of lace a is rotatably supported by means ofga split-bar 6 upon a suitable roll stand 0 and the end of the lace is passed preferably in twisted form. through the pot-eye 51 into the nip between the pressure roll 22 and drum 15 which, in operation, is driven at a high rate of speed, for instance two hundred and fifty yards per minute. The lace accordingly passes through this nip at a very rapid rate and assisted by the frictional surface grip exerted by the drum 15 and roll 22 is shot forward from said drum, or in other words is trajected from the machine in a trajectory which carries it a distance of twelve or more feet, in front of said machine assuming the deflector 29 to be in the highest position of inclination illustrated in Fig. 3. its the deflector gradually moves downwardly, the trajectory described by the lace and the distance it is thrown from the drum 15 is gradually and continuously reduced until the lace is finally trajected forward a mini mum distance to a point perhaps two feet in front of the machine. In this way, and by this means, the deflector, during its pivotal reciprocation, gradually and progressively varies the trajectory described by the lace as it is trajected from the machine so that the lace is folded back and forth, as it were, into the form of the pile d. The machine is roller mounted upon the track 12 and rail 14- in order to enable it to be readily shifted to different locations for piling material thereat or for making a plurality of individual piles at a given point. From the pile (Z the lace is transferred into a conventional kier inany convenient manner. While the machine is primarily adapted for piling lace curtains in predetermined or lrier lots, it may be utilized in many other connections with equal efficiency.

Various modifications in the sequence of the various steps of the method set forth and in the steps themselves and various changes in the mechanism shown and de scribed may be made within the scope of the claims without departing from the nature of my invention.
